The Predator® MagnaDRY™ provides energy-savings, efficient
removal of moisture through a balanced coil design. Because the
unit doesn’t increase sensible cooling, it allows temperatures to
be maintained within the confort zone. Unlike competitive systems, you’re not subjected to over cooling. You save through more
efficient matching of dehumidification and cooling needs. This
makes the MagnaDRY™ perfect for applications that need to
remove large amounts of moisture or maintain low humidity levels.

FEATURES
•
•
Both the unit control board and ignition control board utilize flash codes to aid in diagnosis of unit malfunctions.
Unique alarm codes quickly identify the source of the
unit alarm.
Standard Efficiency– All standard efficiency units have
a minimum EER of 10.5 (3.08 CoP). Gas/electric units
have electronic spark ignition and power vented combustion with steady state efficiencies of 80%.
All units use the same standard filter size. This standardization removes any confusion on which filter sizes
are needed for replacement.
Service Friendly – The Predator® incorporates a number of enhancements which improve serviceability.
The non-corrosive drain pan slides out of the unit to permit easy cleaning. The drain pan is accessed by removing the drain pan cover plate on the rear of the unit.
Once the plate is removed, the drain pan slides out
through the rear of the unit.
The motor and blower slide out of the unit as a common
assembly. This facilitates greater access to all the indoor
airflow components, thus simplifying maintenance and
adjustment.
Service time is reduced through the use of hinged, toolless panels. Such panels provide access to frequently
inspected components and areas, including the control
box, compressors, filters, indoor motor & blower, and the
heating section. The panels are screwed in place at the
factory to prevent access by children or other unauthorized persons. It is recommended that the panels be
secured with screws once service is complete.
Service windows have been placed in both condenser
section walls. Rotation of the cover allows easy access
to the condenser coils for cleaning or inspection.
Johnson Controls Unitary Products
All Predator® units have a second model nameplate
located inside the control access door. This is to prevent
deterioration of the nameplate through weathering.
•
Environmentally Aware – For improved Indoor Air
Quality, foil faced insulation is used exclusively throughout the units.
•
Balanced Heating – The Predator® offers “Ultimate Heating Comfort” with a balance between 1st and 2nd stage
gas heating. The 1st stage of a gas heat Predator® unit
provides 60% of the heating capacity. Balanced heating
allows the unit to better maintain desired temperatures.

265485-XTG-B-1208
•
Convertible Airflow Design – The side duct openings
are covered when they leave the factory. If a side supply/return is desired, the installer simply removes the two
side duct covers from the outside of the unit and installs
them over the down shot openings. No panel cutting is
required. Convertible airflow design allows maximum
field flexibility and minimum inventory.
•
System Protection - Suction line freezestats are supplied
on all units to protect against loss of charge and coil frosting when the economizer operates at low outdoor air temperatures while the compressors are running. Every unit
has solid-core liquid line filter-driers and high and lowpressure switches. Internal compressor protection is standard on all compressors. Crankcase heaters are standard
on reciprocating compressors. Scroll compressors do not
require crankcase heaters. Phase Monitors are standard
on units with scroll compressors. This accessory monitors
the incoming power to the unit and protects the unit from
phase loss and reversed phase rotation.
•
Advanced Controls - Simplicity™ control boards have
standardized a number of features previously available
only as options or by utilizing additional controls.
•
Low Ambient - An integrated low-ambient control
allows all units to operate in the cooling mode down
to 0°F (-17.8°C) outdoor ambient without additional
assistance. Optionally, the control board can be
programmed to lockout the compressors when the
outdoor air temperature is low or when free cooling
is available.
The Simplicity® control board used in this product
will effectively operate the cooling system down to
0°F when this product is applied in a comfort cooling
application for people. An economizer is typically
included in this type of application. When applying
this product for process cooling applications (computer rooms, switchgear, etc.), please reference
applications bulletin AE-011-07 or call the applications department for Unitary Products @ 1-877UPG-SERV for guidance. Additional accessories
may be needed for stable operation at temperatures
below 30° F.
•

Anti-Short Cycle Protection - To aid compressor
life, an anti-short cycle delay is incorporated into the
standard controls. Compressor reliability is further
ensured by programmable minimum run times. For
testing, the anti-short cycle delay can be temporarily
overridden with the push of a button.
Fan Delays - Fan on and fan off delays are fully programmable. Furthermore, the heating and cooling
fan delay times are independent of one another. All
units are programmed with default values based
upon their configuration of cooling and heat.
•
Safety Monitoring - The control board monitors the
high and low-pressure switches, the freezestats, the
gas valve, if applicable, and the temperature limit
switch on gas and electric heat units. The unit control board will alarm on ignition failures, compressor
lockouts and repeated limit switch trips.
•
Nuisance Trip Protection and Strikes - To prevent
nuisance trouble calls, the control board uses a
“three times, you’re out” philosophy. The high and
low-pressure switches and the freezestats must trip
three times within two hours before the unit control
board will lock out the associated compressor.
•
On Board Diagnostics - Each alarm will energize a
trouble light on the thermostat, if so equipped, and
flash an alarm code on the control board LED. Each
high and low-pressure switch alarm as well as each
freezestat alarm has its own flash code. The control
board saves the five most recent alarms in memory,
and these alarms can be reviewed at any time.
Alarms and programmed values are retained
through the loss of power.
•
Reliable – From the beginning – All units undergo computer automated testing before they leave the factory.
Units are tested for refrigerant charge and pressure, unit
amperage, and 100% functionality. For the long term –
All Predator® units are painted with a long lasting, powder paint that stands up over the life of the unit. The paint
used has been proven by a 1000 hour salt spray test.
•
Flexible Placement – All models and configurations
share the same cabinet/footprint and thus the same roof
curb. You have the flexibility to set one curb and choose
the correct tonnage size and heating option after the
internal loads have been determined.
To further simplify planning and installation, Predator®
cabinets are designed to fit your roof. With the optional
roof curb, the unit ductwork is designed to fit around 24”
(610 mm) on-center joists or between 48” (1219 mm) oncenter joists.
The drain pan can be rotated to drain to either the front
or the rear of the unit. Additionally, the drain pan can be
piped to drain through the roof curb. As it is sometimes
difficult to have a level installation, the drain pan features
a generous slope to ensure proper drainage.
•
Full Perimeter Base Rails – The permanently attached
base rails provide a solid foundation for the entire unit and
protect the unit during shipment. The rails offer forklift
access from 3 sides, and rigging holes are available so that
an overhead crane can be used to place the units on a roof.
•
Easy Installation – Gas and electric utility knockouts are
supplied in the unit underside as well as the side of the
unit. A clearly identified location is provided to mount a
field supplied electrical disconnect switch. Utility connections can be made quickly and with a minimum
amount of field labor.
All units are shipped with 2” (51 mm) filters installed.
Johnson Controls Unitary Products

dehumidistat connected to RHTB-1 and RHTB-2 and there is
not a call for cooling, it energizes the hot gas relay (HGR),
which energizes the 3-way valve (SOL 3), the condenser coil
valve (SOL 2), and de-energizes the reheat coil bleed valve
(SOL 1). The Y1 signal is passed to the unit control board
(UCB), which engages circuit # 1, resulting in circuit #1
reheat mode operation.
When the room thermostat calls for first stage cooling, with or
without a call for dehumidification, the RCB senses a signal
through "Y1", de-energizing the HGR, which de-energizes
SOL 3 and SOL 2 and energizes SOL 1, engaging circuit #1,
resulting in circuit #1 cooling mode operation.
When the room thermostat calls for second stage cooling, the
RCB senses a signal through "Y1" & "Y2" and engages circuit
#1 and circuit #2 in cooling mode.
Indoor blower operation is initiated upon a call for first stage
cooling, second stage cooling or dehumidification.
Anytime there is a call for 2 stages of cooling, the unit will not
operate in the reheat mode, even if there is a call for dehumidification at "HUM".
The unit will not operate in the reheat mode if there is any call
for heating.
On units with economizers, the unit will not operate in the
reheat mode if there is a call for cooling and the economizer
is operating as first stage of cooling.
All safety devices function as previously described.
"ALTERNATE” MODE
When the RCB detects a need for dehumidification (24VAC)
at "HUM" via the field supplied dehumidistat connected to
RHTB-1 and RHTB-2, and there is not a call for cooling, it
energizes the HGR, which energizes the SOL 3, SOL 2, and
de-energizes SOL 1. The unit then operates with circuit #1 in
reheat mode and circuit #2 in cooling mode.
•
Burglar Bars - Mount in the supply and return openings
to prevent entry into the duct work.
When the room thermostat calls for first stage cooling while
there is still a call for dehumidification, no operational change
is made. The call for cooling is ignored and the unit continues
to operate with circuit #1 in reheat mode and circuit #2 in
cooling mode.
•
Thermostat - The units are designed to operate with 24volt electronic and electro-mechanical thermostats. All
units (with or without an economizer) operate with twostage heat/two-stage cool or two-stage cooling only thermostats, depending upon unit configuration.
When the room thermostat calls for second stage cooling, the
RCB senses a signal through "Y1" and "Y2" and de-energizes the HGR, which de-energizes SOL 3 and SOL 2, and
energizes SOL 1. Both circuits operate in the cooling mode.
REHEAT MODE SEQUENCE OF OPERATION
The reheat control board allows the user to select two different modes of operation via a jumper connection on the
board. (See Figure 2.) Each mode is described below. Refer
to Figures 2 and 3 when reading this section.
Indoor blower operation is initiated upon a call for first stage
cooling, second stage cooling or dehumidification.
Anytime there is a call for 2 stages of cooling, the unit will not
operate in the reheat mode, even if there is still a call for
dehumidification at "HUM".
The unit will not operate in the reheat mode if there is any call
for heating.
All safety devices function as previously described.

1. Add these resistance values to the available static resistance in the respective Blower Performance Tables.
2. Deduct these resistance values from the available external static pressure shown in the respective Blower Performance Table.
3. The pressure drop through the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of the return
air duct system is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation.
